iptables open port for Azureus


Azureus suggests opening a port within the range of 49152-65535. The first time I booted up Azureus it was using 6881, and it was fine. Then I reboot, and re-opened Azureus, and iptables wouldn't allow it to recieve packages. I wanted to download Xanrdos, but didn't want to cough up $10 for the http download. Anyway, So I tried out the tcp testing tool that comes with Azureus, and I get the NAT error. I check out the tables of NAT, and everything is allowed. I take a look at filter, and everything, except 22, is closed. So I added the following line:
Code:
  iptables -t filter -A INPUT -p tcp --dport 57310 -j ACCEPT
  iptables -t filter -A INPUT -p udp --dport 57310 -j ACCEPT
restarted netfilter, and still nothing. I then tried this out:
Code:
  iptables -t filter -A INPUT -p tcp --dport 57310 -j ACCEPT
  iptables -t filter -A INPUT -p udp --dport 57310 -j ACCEPT
  iptables -t filter -A INPUT -p tcp --sport 57310 -j ACCEPT
  iptables -t filter -A INPUT -p udp --sport 57310 -j ACCEPT
Once again restarted netfilter, and once again no results. So I tried one more thing:
Code:
  iptables -I INPUT -p TCP --dport 49152:65535 -m state --state NEW -j ACCEPT
I restarted netfilter, and again nothing yield. Now I've completely run out of ideas...

When I change the policy to ACCEPT it works fine, so it's gotta be a firewall problem.
